mxfdemux: fix keyframe detection with H264 streams
An index entry should be considered as a keyframe if the flags allow a random access only.
This issue has been highlighted with the following media: dabrain34/gst-integration-testsuites@b4245832
It was picking up a bad key-frame where keyframe_offset was NULL but random_access also.
Edit after merge:
-
merge gst-devtools!243 (merged) -
merge then gst-integration-testsuites!101 (merged)
